Veal calves are at high risk for disease and mortality in early life. Calves face a number of stressors before arriving the grower, including long transport times, which may contribute to poor health. Our objectives were 1) estimate prevalence health outcomes veal on arrival growers Ohio; 2) determine factors arrival, BW auction site (spread across 5 states Northeastern United States); 3) if predict mortality. A physical examination was conducted approximately 30 (mean 45.9 kg [SD 3.0]) from...
Providing optimal calf care remains a challenge on many dairy farms and has important implications for the future health, welfare, productivity of male female calves. Recent research suggests that calves receive lower quality early in life than calves, but further investigation is required to determine factors influence this disparity. The objectives study were understand producer perspectives neonatal practices explore differences between care. Overall, 23 producers Ontario, Canada,...
Compared to other enrichment modalities, relatively few studies have been conducted evaluate sensory stimulation as environmental in dairy cows. The aim of this study was explore the effect music played milking parlor on behavior and parameters cows during afternoon milking. Ninety-one Jersey were introduced one five treatments, including no or classical, country, Latin, rock genres, over four 5-day periods a switchback experiment. One treatment applied per day. amount milk harvested from...
A cross-sectional study was conducted to characterize and evaluate dairy producers’ attitudes practices on antimicrobial use (AMU) resistance (AMR).
Abstract The National Beef Quality Audit (NBQA)-2022 serves as a benchmark of the current market cow and bull sectors U.S. beef industry allows comparison to previous audits method monitoring progress. From September 2021 through May 2022, livestock trailers (n = 125), live animals 5,430), post-slaughter hide-on 6,674) were surveyed at 20 commercial processing facilities across Cattle transported in variety trailer types for an average distance 490.6 km mean transport time 6.3 h. During...
Abstract Previous research has shown surplus dairy calves arrive at ‘formula-fed’ veal operations in North America sub-optimal condition; however, little is known about the condition of ‘bob’ on arrival abattoirs. The objectives this study were to assess bob an abattoir Ohio and determine risk factors for poor health outcomes. On arrival, 35 each 12 cohorts (n = 420 calves) assessed using a standardised examination. A blood sample was also collected failed transfer passive immunity (FTPI)...
Gastrointestinal disease is the most common cause of mortality in dairy calves. Septicemia an important sequela diarrhea, and possibility bacteremia primary justification for empirical antimicrobial therapy. Prior reports estimate that approximately one-third diarrheic calves are bacteremic; however, those estimates may not be representative routine cases heifer on commercial operations early course disease. We hypothesized prevalence with diarrhea systemic signs illness less than prior...
The primary objective of this study was to compare male and female dairy calf management practices evaluate risk factors associated with differences in care. Secondary objectives were understand surplus transportation marketing investigate incentives motivate care improvements. An online survey distributed all producers Ontario (n = 3,367) from November 2020 March 2021 Atlantic Canada 557) April June 2021. Dairy identified through provincial associations contacted via e-mail social media....
In North America, surplus dairy calves are sold soon after birth and often marketed through a third party (e.g., live auction, livestock dealer) before entering veal or beef production. Previous work has demonstrated that percentage of have failed transfer passive immunity (FTPI) clinical signs disease on arrival at calf-raising facilities, but little is known regarding calf condition during marketing. The objectives this cross-sectional study were to (1) estimate the prevalence FTPI poor...
Optimal early-life care of surplus calves born on dairy farms is critical for health and welfare. This cross-sectional study aimed to describe the marketing practices male calves, differences in colostrum management between female farms, relationship discrepant producers' attitudes toward calf care. US producers (n = 1,000) states Florida, Michigan, Ohio, Vermont, Wisconsin were selected using stratified random sampling. A questionnaire containing questions about farm demographics,...

Two experiments were conducted to investigate the effects of alternative housing and feeding systems on behavior performance dairy calves. Thirty-four female Holstein calves housed in hutches Exp. 1, 48 wire-panel pens a feed-commodity shed 2. All allocated treatments at birth (ranging from 3 9 d age) monitored for wk. Treatments as follows: individual fed with bucket, bottle, paired or bottle. Milk was via bucket bottle twice per day (6 L/d). Direct observations once week all 1 video...
Abstract The objective of this study was to determine the impact 0, 1, 2, or 3 d oral electrolyte solutions (OES) following transport on calf behavior, biochemical measures hydration, and subsequent health. Two cohorts 60 Holstein bull calves ~3 7 age were included in experiment. Calves (n = 30/treatment) randomized 1 4 treatments arrival at a calf-raising facility: (1) 1-d OES, (2) 2-d (3) 3-d (4) no OES (control). evaluated for signs arthritis, depression, dehydration, diarrhea, fever,...
Abstract The National Beef Quality Audit – 2022 serves as a benchmark of the current fed steer and heifer population U.S. beef industry allows comparison to previous audits method monitoring progress. In-plant cooler assessments collections carcass data took place from July 2021 November 2022. During in-plant evaluations, 10% 1-d production was surveyed for quality yield indicating characteristics carcasses (n = 9,746 carcasses). Distributions sex classes among sampled were (65.0%) (35.0%),...
Abstract The study objective was to investigate the effect of repeated hypothalamic–pituitary–adrenal (HPA) axis stimulation using synthetic adrenocorticotropic hormone (ACTH) intramuscular injections on hair cortisol concentration, growth, and behavior in preweaned dairy calves. Twenty-seven Holstein calves were assigned nine triads (based sex birth order) randomly 1 3 treatments: 1) control (CON; 2 mL saline weekly); 2) moderate (MOD; alternating Cosyntropin [2 mcg/kg body weight (BW)] or...
